Subject: spice: connection events.

This patch adds support for connection events to spice.  The events are
quite simliar to the vnc events.  Unlike vnc spice uses multiple tcp
channels though.  qemu will report every single tcp connection (aka
spice channel).  If you want track spice sessions only you can filter
for the main channel (channel-type == 1).
